Failure to active DNS

Hi All!!
I have a problem, when i click in "dns servers" in the "services" menu, an error occours, this:
Warning: main(guiconfig.inc) [function.main]: failed to open stream: No such file or directory in /usr/local/www/pfswww/packages/config/tinydns/tinydns_status.php on line 32

It seems that nobody has responded to this problem in quite a while. I ran into the same problem. First I thought it has to do with installation problem or missing some library, but I tried reinstalling the DNS Server module and still got the same problem. All of my other features are working OK. Can anyone at least suggest the nature of this problem?

I have read on other thread about some other issues with DNS server so obviously the module is working for some people.
